Conospermum Undulatum: Insights Into Population Genetics And Pollination Ecology Of A Threatened Species, Nicola Delnevo

Theses: Doctorates and Masters

Fragmentation of natural vegetation is currently one of the largest threats to biodiversity. Within the southwest Australia global biodiversity hotspot, the Swan Coastal Plain was historically cleared for agriculture and forestry and is now experiencing extensive land clearing for urbanisation. The wavy-leaved smokebush Conospermum undulatum is a rare species endemic to the Swan Coastal Plain, and its future persistence is threatened by urban expansion.

Throughout this research, I investigated the pollination ecology of this species and found a specific association between C. undulatum and native bees for pollination. I also demonstrated that C. undulatum has evolved pollen with resistance to …

Ecology Of Feral Cats Felis Catus And Their Prey In Relation To Shrubland Fire Regimes, Tim S. Doherty

Theses: Doctorates and Masters

Invasive predators are major drivers of global biodiversity loss and their impacts may be worsened by other disturbances such as fire. I examined how the fire history of shrublands influences the ecology of feral cats Felis catus, dingoes Canis dingo and their prey species in Western Australia’s northern Wheatbelt region.

A review of the literature revealed that feral cats inhabit a diverse range of ecosystems worldwide, but are generally recorded most often in habitat types characterised by a mixture of plant growth forms close to ground level. Cat habitat use is influenced by predation/competition, prey availability, shelter availability and …

Systematics And Biogeography Of The Australian Burrowing Freshwater Crayfish Genus Engaewa Riekk (Decapoda: Parastacidae), Quinton Burnham

Theses: Doctorates and Masters

The overall aim of this study was to explore the systematics and biogeographic patterns of the freshwater crayfish genus Engaewa Riek, a strongly burrowing freshwater crayfish restricted to the coastal corner of south-western Australia (SWA). The genus Engaewa is a Gondwanan relict with great potential as a marker of historical processes, due to its high habitat specificity and low dispersal ability. This study comprises an extensive taxonomic and phylogenetic revision of the genus Engaewa (using both molecular and morphological data), a detailed study of its distribution and uses the knowledge gained to explore biogeographic patterns in the biodiversity hotspot of …

Seeing Through Others' Eyes : Towards A Hybrid Ecology Of Marine Turtle And Dugong In Australia, Zoe Car

Theses: Doctorates and Masters

This thesis explores the conflict between conservationists and Indigenous communities over the hunting of marine turtles and dugong in Australia, with a view to finding a way to overcome the barriers that prevent the resolution of this issue. I approached this exploration as an ecologist, using the framework of Berkes (2004) who proposed three shifts for the field of ecology. This meant taking a systems approach and investigating the intertwining threads of the issue as possible, with a specific focus on integrating the human aspects of the problem in a participatory manner. By doing so my work entered into a …
